VAPOR-BU RN ER FOR STOV ES SPECIFICATION forming part a Letters PatentNo. 613,347, dated November i, 1898.

Application filed March 26, 1898. Serial No. 6'75 ;252. (No model.)

To ctZZ whom it may concern.-

Be it known that we, FERNANDO 0. WIN- GETT and ANDREW J. BLAOKWOOD,residing at Sterling, in the county of Rice and State of Kansas, haveinvented certain new and useful Improvements in Vapor-Burners forStoves, &c., of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to burners for vaporburning stoves.

The objects of the invention are to produce a burner in which vaporshall be developed rapidly and in which the air to support combustionshall serve as a covering to the liquid-vapor supply until near the timefor developing into vapor, thus preventing overheating; also, to improvethe construction of such burners.

Figure 1 is a broken vertical section of a heating-stove with burnerapplied. Fig. 2 is a perspective of the flame-shield and supports. Fig.3 is a broken perspective of lower part of reservoir and connections.Fig. 4 is a broken perspective of dish, plate, and air-pipe passingthrough the same.

The stove-body A and legs or supports B may be of usual construction,although we have devised a stove with internal pipes to which thisburner is particularly adapted. It is preferable that the stove-body beat its lower end generally circular and tapering upward; but this is notimperative. The parts of the stove are generally of thin metal.

The burner can be used in any heater or cook-stove and changed in formto suit the va. rious stoves.

The stove-bottom or drip-piece C has a central air-tube D firmlyconnected thereto. At the upper end this tube has side perforations D,and the tube D supports and is closed by the bottom plate E of thedouble convex gasreservoir. The top plate E of this reservoir isconnected to the bottom plate by a gastight joint, and in some cases thereservoir may be cast integral and may be made in oblong form forcooking-stoves or furnaces.

The supply-pipe F, which conveys the supply of hydrocarbon liquid or gasto the reservoir, passes centrally through the pipe D and extends intothe reservoir E. Inside the reservoir the pipe F is preferably closed atthe top and has a number of side openings F, which tend to distributethe entering liquid or vapor in the reservoir. Thus openings from pipe Dconvey air outwardly under the bottom of the reservoir, while theopenings from pipe F convey liquid or vapor into the reservolr.

The pipe F is supplied with liquid hydrocarbon in usual manner and has ashut-off valve, as usual. Whether this material onters the reservoir inform of a liquid or vapor it is soon formed into avapor when the burneris in use.

From near the top and inside of the reservoir E two or more pipes Hextend downwardly through the bottom plate and then curveinwardly. Thesepipes may terminate in burners H, as shown in Fig. 3, or the pipes maybe connected to an annular tube I, having a series of holes pointinginwardly, as in Fig. 1. In either case the pipes H will take in vaporfrom near the top of the reservoir and will convey it to a burner whichdirects the vapor generally toward the central airtube D. This has theeffect to heat the air in tube D and cause it to rise rapidly in suchtube and pass out against the lower plate of the reservoir, where itmingles with the flame from the burners and passes outwardly and uparound the edge of the reservoir.

A reversed hollow frustum or shield K is suspended from the reservoir Eby bars L, and the lower edge of this shield is preferably a littlebelow the burner. This shield prevents air-currents close to the burnerand induces a steady, even, and quiet combustion, while permitting theair to reach the flame from below and permitting the flame to pass outaround the reservoir, the suspensory devices L ofiering littleresistance.

The vapor-supply is first developed by the application of temporary heatin usual manner. As soon as Vapor has developed in reservoir E, underthe influence of heat, this va por will be driven out the pipes H to theburners H or I, where it is ignited. The burners facing inwardly towardthe pipe D cause the air therein to become heated and flow out theapertures D. At the same time the action of the heat on the lower partof the reservoir E rapidly develops vapor in such reservoir. The supplyof hydrocarbon through pipe F regulates the combustion. The form of thereservoir E gives it special value in deflecting the flame outwardly andin developing the vapor internally, and the vapor-supply being takenfrom near the top of the reservoir insures that the purest and rarestvapor in the reservoir shall be conveyed to the burners.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A burner for hydrocarbon vapors and gases, consisting essentially ofa double convex reservoir having a central liquid-supply pipe with sideopenings inside the reservoir,

exit-pipes extending downward from the upper part of the interior of thereservoir to burners directed toward the supply-pipe below thereservoir, and an air-pipe surrounding the liquid-supply pipe, open atthe bottom and terminating below the reservoir, said air-pipe havingair-openings immediately below the reservoir, substantially asdescribed.

2. The burner described having its inner liquid-pipe leading to thereservoir, the outer air-pipe surrounding the liquid-pipe and hav-' ingits inlet-opening below the burner, and air escape openings below thereservoir, burner-pipes leading down from the reservoir and havingburners directed toward the central air-pipe, and a shield surroundingthe burners, all combined substantially as described.

3. In ahydrocarbon-burner, the convex reservoir, liquid-pipe enteringthe same centrally and air-pipe surrounding the liquidpipe with inletbelow the burner and outlet below the reservoir, burners connected tothe reservoir and directed toward the air-pipe,- and the frusto-conicalshield supported from the reservoir, all substantially as described.

In testimony whereof we affix our signa-' tures in presence of twowitnesses.
